UV map not applying on Object
Duplicated Material output node

Even though it seems to be one, if you try to grab it and move it slightly you should discover that there's another one just behind it.




When you have multiple material output, Blender set as active the last selected of them. As in your setup Shader/Surface and Displacement are in different output node, you cannot see both effect at the same time.

Delete one material output node and plug the cables in the other.
